Answer:
Option B is the answer.
Step-by-step explanation:
The graph attached shows the relation between the numbers of people in a group and cost of the tickets.
Slope of this line will represent the unit rate of admission ticket.
Since this line passes passes through two points (0, 0) and (1, 15)
Therefore, slope of the line will be = [tex]\frac{y-y'}{x-x'}[/tex]
= [tex]\frac{15-0}{1-0}[/tex]
= 15
Therefore, $15 is the cost of one admission ticket and (1, 15) is the point showing unit rate.
Option B will be the answer.
